MSC Romax 2025.1

MSC Romax 2025.1

MSC Romax is the industry-leading specialized software for the design, simulation, and analysis of mechanical drivetrain systems, with a particular focus on gears, bearings, shafts, and complete gearboxes/transmissions. It provides an integrated environment for modeling these complex systems, performing detailed analyses for durability, efficiency, noise, vibration, and harshness (NVH), and optimizing designs for performance and reliability. Romax combines advanced analytical methods with multi-body dynamics and finite element analysis to predict system behavior under real-world operating conditions, making it essential for developing everything from electric vehicle reducers and wind turbine gearboxes to helicopter transmissions.

It is the de facto standard tool for engineers who need to ensure the durability and quiet operation of power transmission systems.

Primary Users: Gear Design Engineers, Transmission Engineers, Bearing Engineers, and Rotating Machinery Specialists in automotive, aerospace, wind energy, and industrial sectors.

Key Features & Capabilities

Romax provides a complete, system-level approach to drivetrain engineering.

Core Design & Analysis Modules:

1. Gear Design & Analysis:

   • Detailed Tooth Contact Analysis (TCA): Predicts load distribution, contact patterns, transmission error, root stresses, and contact stresses for spur, helical, bevel, and hypoid gears.

   • Micro-Geometry Optimization: Automatically optimizes gear micro-geometry (profile/lead modifications) for low noise and high durability.

   • ISO/AGMA Standards: Calculations compliant with international gear rating standards.

2. Bearing Analysis:

   • Advanced Bearing Models: Detailed analysis of rolling element bearings (ball, cylindrical, tapered) considering clearance, preload, and misalignment. Includes proprietary bearing stiffness calculation.

   • System-Level Bearing Loads: Calculates accurate bearing loads within the complete housing and shaft assembly.

3. Shaft & Housing Analysis:

   • Integrated FEA: Built-in finite element solver for analyzing shaft bending and housing deformation under system loads. Supports flexible housing models for accurate system deflection.

4. System NVH & Dynamics:

   • Dynamic Simulation: Predicts gear whine, rattle, and overall NVH performance through forced frequency response analysis.

   • Acoustic Radiation: Estimate sound power radiation from the gearbox housing.

5. Durability & Efficiency:

   • Duty Cycle Analysis: Assess component life (gear pitting/scuffing, bearing L10 life) under complex, time-varying load spectra.

   • Power Loss & Efficiency Modeling: Calculate no-load and load-dependent power losses (gear mesh, bearing, seal, churning, windage) to optimize transmission efficiency.

What’s New in 2025.1:

• Performance Enhancements: Faster solver times for large, complex system models.

• Improved User Interface & Usability: Workflow refinements and updated graphics.

• Enhanced Physics Models: Updates to gear contact, bearing, and efficiency models based on latest research.

• Expanded Electric Drivetrain Tools: Continued focus on tools for e-axle and e-drive development, including motor excitation modeling.
